For the rear surround, what is the equivalent premium option replacement part number to consider? Since I'm going to be cutting the mount brackets I'd like to upgrade the rear surrounds too.
The bracket part is EX53-18808-AE, but I am not sure if that's the tweeter alone or the whole assembly.
I am wondering if the upgraded center with mid+tweeter combo (AW93-18808-EC) could also fit these surrounds?

I upgraded to the premium/autobiograpgy for doors (tweeter, mid, woofer) and it's a noticeable improvement.
Rear sub (non-OEM) upgrades coming soon.
